CAR-COUPLING.

SPECIFICATION formingpart of Letters Patent No. 290,656, dated December 18, 1883.

Application filed March 7, 1883. (No model.)

I0 all whom it may concern):

Be it known that I, MARTIN E. SWART, a citizen of the United States, residing at Denver city, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Gar-Couplings, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in car-couplings, by which each draw-head is provided with a link and standard, which take the place of coupling-pins adapted to connect one car with another, under ordinary circumstances, by moving the cars together, avoiding the danger incurred by going between the cars to guide the link and set the pin. These objects I attain by the use of the device illustrated in the accompanying drawings, forming a part of this specification, in which Figure 1 is a perspective view showing the lever by which the cars may be uncoupled from the roof; Fig. 2, a perspective view showing the lever by which cars may be uncoupled from the side; Fig. 3, a sectional side view, showing the device forming a double coupling; Fig. 4, an inverted view of Fig. 3, having the lid removed; Fig. 5, a perspective side view, showing the position of the lever and coupler when uncoupling. Fig. 6 is a front View.

Similar letters refer to similar parts throughout the several views.

Ais a draw-head, having a solid bottom, a, and solid sides a a, in the construction of which a standard, B, projects upward from the bottom, terminating at a line equal to the top ofthe sides a a. The standard is tapered from the front base at b to the terminus at d. The back portion of the standard B from cl to e may be slightly concave, or may be provided with shallow notches to correspond with the shape of the coupler D, which is made in the form of a clevis, having the two ends turned outward through the sides of the draw-head, as shown at F,

to form arms on which the coupler may be raised or lowered, and to one of which is is connected with a pull-bar, K, having a hinge, k. The pull-bar K is attached to the end of the car by means of cleats L L, through which it is made to slide easily, and is pro-' vided with a ring at the top of the car, by means of which the coupler may be disengaged from the standard in the drawbar of the next car. The weight of the pull-bar also servesv the purpose of preventing the coupler from jarring off the standard when the cars are in motion, and not drawing on the coupler. A lid, 0, may be attached to the draw-head by means of a common or a spring hinge at G, for'the purpose of preventing rain or'snow from getting into the recess in the draw-bar around the standard.

As will be seen by reference to the drawings,the front ends of the couplers are pointed, as at the lip z, in order that, though coming in a line, one will pass under the other, and when brought in contact with the sloping front of the standard 13, it is made to slide upward until it drops over the standard, when the coupler on the opposite car will drop back and rest on the lid 0, or may be dropped over the standard by raising the lid. The latter may be entirely dispensed with, except during the season of snow and freezing.

Cars having this coupling are readily coupled to other cars using link and pin by using the common link or this coupler.

I am aware of the invention by others of devices for coupling ears automatically. I do not therefore claim such a combination,broad- 1y; but

WVhat I claim as new, and desire to secure by Letters Patent, is-

1. In a draw-head, the U-shaped coupler D, having the outward bent ends F, journaled in the sides of the draw-head, and short In testimony whereof I affix my signature in presence of two witnesses.

arm I, attached to one of said ends F, substantialiy as described.

2. In a draw-head, the U shaped coup- ]er D, journaled in the sides of the draw-head, having the short arm I, and at its forward end the lip i, combined with lever H, and a 1 suitable lifting device, substantially as shown and described.
